In contrast, FQE is full quantum computer algorithm [1]}, which is based on the linear combination of unitaries formalism [2]}. FQE performs all calculations on a quantum computer, avoiding the slow and tedious switching between classic and quantum computers. FQE has been demonstrated in chemistry calculation [1]}, and attracted attention in recent years [4]}, [5]}, [6]}, [7]}, [8]}, [9]}.
